I have looked high and low for some fanfold foam here on the central coast, Santa Barbara area, in California with no luck. I own and operate an ACE Hardware store and can order it direct for Owens Corning but I have to order about $2000 worth to get them to ship it. Home Depot and Lowes do not carry it in our area and I want some. If anyone knows of a place to find some I would appreciate it.
